The HB Series Explosion-Proof Electric Hoist is engineered for the most demanding and hazardous industrial environments.
Designed with safety as the paramount priority, this HB series explosion-proof electric hoist ensures reliable and efficient material handling in areas where flammable gases, vapors, dust, or fibers may be present. It combines superior explosion-proof technology with high-performance lifting capabilities to protect both your personnel and your assets.
Certified Explosion-Proof Protection:
The hoist’s critical components—including the motor, control box, emergency limit switch, and electrical enclosures—are encased in specially designed housings that prevent any internal spark or high surface temperature from igniting the surrounding atmosphere.
Complies with international explosion-proof standards such as ATEX (for Europe) and IECEx, often certified for Zones 1, 2, 21, and 22.
Robust and Durable Construction:
Built with high-strength materials to withstand corrosive and harsh environments. Key components are often made of non-sparking materials like copper alloys or stainless steel to prevent ignition risks.
Enhanced Safety Features:
Equipped with a dual braking system featuring an independent mechanical load brake and an electromagnetic brake, providing fail-safe operation and precise load control.
Includes upper and lower limit switches to automatically stop the hoist at its maximum and minimum heights, preventing overtravel and accidents.
Thermal protection in the motor guards against overload and phase failure.
High Performance and Efficiency:
Features a high-torque, explosion-proof motor that ensures smooth start-up, stable operation, and powerful lifting capacity.
Low Headroom design maximizes lifting height in confined spaces.
Precision-machined gearing ensures smooth and quiet operation with minimal vibration.
User-Friendly Operation:
Operated via a low-voltage, explosion-proof pendant control station with clearly marked buttons for up, down, and traverse directions. The control is ergonomically designed and responsive.
Options for radio remote control are available for added operator safety and convenience.
Low Maintenance:
Sealed components protect against dust and moisture ingress, reducing wear and tear and extending the service interval.
Designed for easy inspection and maintenance to minimize downtime.
Note: Parameters are typical and may vary by specific model and manufacturer. Always consult the official product manual.
